Schneider Electric C160H450FM – ComPacT NS1600H 4P 1600 A MCCB, 70 kA at 415 V AC, MicroLogic 5.0 trip unit.
Description
About the C160H450FM
About the C160H450FM
The Schneider Electric C160H450FM is a 4-pole, 1600 A ComPacT NS1600H moulded case circuit breaker rated for a breaking capacity of 70 kA at 380/415 V AC. It carries a MicroLogic 5.0 electronic trip unit with long-time, short-time and instantaneous (LSI) protection and an operational voltage of 690 V AC, suited for fixed, manually-operated distribution boards up to 1600 A.

Selection Notes
The MicroLogic 5.0 trip unit decodes to long-time overload (L), short-time delay (S) and instantaneous (I) protection, giving the C160H450FM adjustable short-time discrimination with downstream breakers in a 4-pole, 1600 A NS1600H frame. Zone selective interlocking is not available on this trip unit, so fault clearance relies on the Isd time-delay setting instead of a ZSI link. Choose this 5.0 (LSI) version over the 2.0 (LI) sibling when short-time coordination is required, or over 6.0 (LSIG) when ground-fault protection is not needed in this circuit.
